Rock Slide (Japanese: いわなだれRock Slide) is a damage-dealing Rock-typemove introduced in Generation I. It was TM48 in Generation I before losing its TM status in Generation II. It regained its TM status, albeit as TM80, in Generation IV onwards.

Nosepass's body becomes outlined in blue and a nearby rock also becomes surrounded in blue and it floats into the air above the opponent. The rock then splits apart and the pieces come falling down on the opponent.

Dwebble jumps high into the air and raises both of its claws straight up into the air. Multiple white rings of energy then appear above and around Dwebble's body and large grey boulders come out of the ripples of energy. The boulders then fall down and rain over the opponent.

Crustle raises both of its claws into the air. Then, multiple white rings of energy then appear above Crustle's body high in the sky and large grey boulders come out of the ripples of energy. The boulders then fall down and rain over the opponent.

Nosepass lifts its arms into the air and several rocks around it float into the air around it. The rocks then explode and form a mixture of sand and boulders. The mixture then rains down on the opponent.
